Peterson: Can't explain lie-detector results

September 29, 2008

Former Bolingbrook police sergeant Drew Peterson said today that he was unable to explain why a polygraph exam showed he was deceptive in answering questions about the Oct. 28 disappearance of his fourth wife, Stacy.

Appearing on CBS' "The Early Show," Peterson said the test showed he was deceptive on the last time he saw his wife, if he knows where she is and if she had called to say she was leaving.

Peterson said he passed all other questions on the test, which was part of an interview for a book, "Drew Peterson Exposed," due out Wednesday.
